A Sacred Heart University poll of 502 Connecticut voters, released Thursday, found a tighter lead in the gubernatorial race for Democrat Ned Lamont, compared to a Quinnipiac Poll released the same day.

Sacred Heart found that unaffiliated voters are dividing their support for the two candidates, at 29.8 percent each. More than 27 percent of unaffiliated voters said they were undecided.

Female voters expressed more support for Lamont than Stefanowski, at 49.3 percent to 30.1 percent, respectively. However, more males support Stefanowski (43.9 percent) than Lamont (31.4 percent).

Sacred Heart said the top issues driving voters' thinking are the state's high overall tax burden and budget crisis.

Half of those polled either strongly or somewhat agree that electronic highway tolls that collect revenue from in-state and out-of-state drivers could be an effective way to pay for highway improvements and relieve traffic congestion.

In addition, 66.3 percent said they strongly or somewhat agree that it would be fair to raise taxes on those with incomes of more than $1 million, should the state be unable to solve its budget crisis by cutting services and spending.
